It sounds like you should keep your radio, add the rca adapter, add a sub amp and some subs, and replace the stock speakers, if you are unsure about changing out the door speakers just change out the dash speakers. they will make the most difference and they are super simple to swap out. and you could always add the kicker amp upgrade if you want a little more power with minimal hassle

Which is super gay because this taps into your speaker wiring for the rear speakers and converts it into a RCA for amps. I never liked this way off adding RCA outputs to a system as i feel they distort and just wont be good.

I am installing some very nice subs ((3) 8'' Digital Design) and i dont wont to have any problems with the low pass feed for them.

I guess if i want quality i am will need to replace the Head Unit so I have RCA pre-outs.

Has anyone ever used these interface modules that taps into speaker wires to get RCA outputs????

it sounds like you are married to that stock deck if you want to keep your back up camera, rear dvd and u connect. and you can keep good sq with your stock deck. crutchfield cant be the only people in the world that has them. also there are many manufactures that make clean sweep systems like jl audio produce. just call http://www.sonicelectronix.com/ and they will sett you up with a much better way than the old "splice into the rear speaker wires"
and calm down its really not that hard. dont make it more than it really is have fun with it. thats what its all about.

Yea i know it does seem like I am married to the head unit. Im not opposed to changing it but rather keep it and spend the money on new speakers and stuff. Knowing me i will spend wayyyyy to much on a head unit. I wish i could put the new touch screen head units in they have on the newer jeeps...

well leave it in, do all the installation you want (subs, amps, speakers, ect..) and you can always change the deck out in the future if you want. its just that easy.
but i vote to keep it. if you do all the upgrades correctly you will never need to change it out.
